It’s a cold, chilly night, and you realize that one of your radiators isn’t exactly giving off enough heat as it should. But the rest seem to work just fine.

So, if you happen to be asking yourself, why is my radiator not working? Then you are on the right page. The video will give you a brief synopsis of this type of problem.

Firstly, you need to ensure that the valves are open on both sides of the radiators. That allows heat to come through to the radiator and encourages heat circulation. On the other hand, other issues that may arise could come from sludge issues. These could occur within the heating system, a faulty pump in an open vented system or a fading pump. It would result in the inability to push the heat to the furthest radiator. There may even be several other issues, such as a trapped TRV pin and things along those lines. But, an engineer can visit you and investigate this. They will need to come to the property, see the problem and then be able to solve the problem for you. Read on to find an answer to why is my radiator not working?

What do you do when one radiator is cold?

First, determine whether the entire radiator or part of it is. If you feel that the top part is cold while the bottom part is hot, it could be due to air stuck inside. When there is air inside, it tends to hinder the space initially intended for hot water. The air inside wouldn’t allow proper circulation. That is why you may need to bleed the radiator. Usually, it is essential to be regular with clearing your radiator of any air stuck inside. Doing this at least twice a year is the way to go. Check out our blog to find out how often should you bleed radiators?

Another reason for this problem could be due to the build-up of debris inside the radiator. You will need the help of a boiler engineer to do this for you. They will need to remove the radiator and flush its inside. You can also attempt to do it yourself if you’re up for the task. It may be a little tedious. However, if you aren’t sure, we recommend getting an engineer to sort it out.

How do you fix a radiator that won’t heat up?

Once you’ve determined that your heating system is working correctly, try to see what other problems persist. Suppose the entire radiator network is not working. In that case, the best thing to do is to call a professional boiler engineer. You may need to have an expert take a look at it. As mentioned above, if a radiator is not heating up, it could be due to air trapped inside. Lack of bleeding in your radiator could be a reason for the lack of heat. All you have to do is to use your radiator key and unscrew the valve you will notice on the top side of the radiator.

Turn it slowly till you hear a hissing sound. That will indicate the air escaping the radiator. Make sure to crew it back once you feel water coming out. Have a piece of rag or napkin nearby. A dish to catch the escaping water will also come in handy. You don’t want to make a mess of this. So, this should do the trick. If you still feel like it hasn’t helped the radiator heat up later, it’s best to call an engineer. We hope this blog helped answer your query – why is my radiator not working?
